REINFORCED BUILDING PAPER y Filed Aug. s, 1956 Patented Jan. 3, 1939UNITED STATES PATENT OFFICE 3 Claims.

This invention relates to building construction and has specialreference to reinforced building paper.

One important object of the invention is to provide a novel form ofreinforcement for building paper peculiarly adapted to hold plasterapplied to the building paper, the reinforcement being so arranged thatthe plaster will key thereto.

A second important object of the invention is to provide a novelbuilding paper reinforcement constructed of thin metal strips.

A third important object of the invention is to provide a novelarrangement of building paper and reinforcement wherein the buildingpaper and reinforcement are secured together in a novel and improvedmanner.

With the above and other objects in view, the invention consists ingeneral of certain novel details of construction and combinations ofparts hereinafter fully described, illustrated in the accompanyingdrawing and particularly pointed out in the claims.

In the accompanying drawing like characters of reference indicate likeparts in the several views and:-

Fig. 1 is a face View of one unit or sheet of building paper andreinforcement constructed in accordance with this invention.

Fig. 2 is a bottom edge view of the sheet shown in Fig. 1.

Fig. 3 is a magnified detail section on the line 3--3 of Fig. 1.

Fig. 4 is a similar section on the line 4-4 of Fig. 1.

In the embodiment of the invention here illustrated there is shown asheet I0 of building paper which is supplied with vertical reinforcingmembers indicated in general at II and horizontal reinforcing membersindicated in general at I2.

As here shown but two vertical and two horizontal reinforcing membersare shown but it is to be understood that as many vertical and as manyhorizontal members may be used as is found convenient to reinforcewhatever sized sheet of building paper is adopted. The principles of theinvention are, however, clearly shown in the present disclosure.

Each of the members II consists of a strip of thin metal trough shapedin cross-section and having a flat bottom I3 and flat outwardly fiaringsides I4. At intervals along the bottom I3 slits of invertedsubstantially U-shape are formed to provide tongues I5 integral at theirlower ends with the bottom I3. These tongues are bent up and over thetransverse members I2 which lie on (Cl. 'Y2-116) the edges of the troughsides I4. The ends of the tongues I5 are bent down as at I6 to hold themembers I2 in place.

Each of the members I2 is formed from a strip of thin metal havingspaced arch portions I1 which are connected by flat portions I8. Theportions I8 lie in the plane of the trough bottoms I3 and the troughbottoms and these portions lie flat on the sheet of building paper. V-shaped slits I9 are spaced along the portions I8 and trough bottoms I3to form pointed prongs 20 which pass through the building paper and areflattened thereagainst to lock the paper and reinforcement together.

In use the sheets are secured to the studding, rafters or the likebuilding elements by staples straddling the members Il, nails driventhrough these members or in other desired manner. When thus securedplaster applied to the reinforced face of the device will key under thetrough sides I4 and the end portions of the arches II so that it is rmlyheld in place.

There has thus been provided a simple and elcient device of the kinddescribed and for the purpose specified. 25

Changes may be made in the proportions and details of the invention sothat the invention is not restricted to the exact four here shown anddescribed but includes all forms which come with the scope of theappended claims.

What is claimed, is:-

1. In a reinforced building paper sheet, reinforcing means comprisingspaced vertical strips of their metal provided with upwardly extendingtongues and paperholding prongs, and spaced horizontal thin metal stripscrossing said vertical strips and secured thereto by said verticaltongues, said horizontal strips being provided with spaced paper holdingprongs extending from the strips in a direction opposite the saidtongues. 40

2. In a reinforced building paper sheet, reinforcing means comprisingspaced vertical strips of their metal provided with upwardly extendingtongues and paper holding prongs, and spaced horizontal thin metalstrips crossing said vertical 45 strips and secured thereto by saidtongues, said horizontal strips being provided with spaced paper holdingprongs, said vertical strips being trough shaped in cross-section withthe sides of the trough flaring outwardly from a at bottom and thehorizontal strips being arched over the vertical strips and having theportions intermediate the arched portions in the plane of the troughbottoms.

3. In a reinforced building paper sheet, a series prongs projecting fromthe vertical and horizontal strips in a direction opposite the verticalstrips, a building paper held by the last prongs against the strips inthe plane of the flat portions thereof.
